<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top">Rick,<br/><br/>I have an accurate CAD model of a stock 350 hull and pods with assigned material densities. The software can make short work of determining changes in the longitudinal CG and what effects shifting the pods have. We would have to agree on a vertical datum, say the surface Edge of a hemihead for example. <br/><br/>As it lays now, the CG is right under the pilots butt, but it looks like George did not account accurately for the changes in buoyancy once launched. The trick would be trying to guess how far back to shift the CG. I can do this for you on my next group of days off if you'd like.<br/><br/>However, I like James idea of external movable weights as a better solution because you still have this 400 lb light condition to contend with anyway.<br/><br/>Joe<br/><br/>Sent from Yahoo!

<div>I haven’t attached my pods yet to the pressure hull and after hearing about
the aft positive buoyancy issue from a number of K-350 owner/builders I am now
contemplating moving my pods aft one frame. I have all ready installed my drop
weight threw hulls so I would have to extend the cross bar forward that goes
between the pods for that plus not having any engineering experience, it would
purely be a guess on what it would do to the trim. I doubt it would have the
reverse effect and transfer the buoyancy problem to the front but not sure.
</div>
<div>One thought I had was to bolt them on per plans but be able to adjust them
aft as needed to attain the proper trim and then when I find the magic spot,
weld in the bell reducers I have and connect the power cables. Any thoughts out
their pro or con?</div>

im going to do is fix 100Kg under the aft tank, and then make the rest in blocks
that can be moved around. Then divers can place them with straps to the
underside somewhere until its balanced. Will make the blocks at the
weekend. <br clear="none"><br clear="none">

<div>Hi All,</div>
<div> </div>
<div>I got my boat in the water at the weekend for the first time.
Put the pictures up here.</div>
<div> </div>
<div><a rel="nofollow" shape="rect" target="_blank" href="http://www.guernseysubmarine.com/operations.htm">http://www.guernseysubmarine.com/operations.htm</a></div>
<div> </div>
<div>I didnt get any leaks at all, so i was super happy. I wasnt
really expecting to try and dive and would have been happy with just no
leaks and a float test, but everything worked fine, so i gave it a
go. Unfortunately i didnt have enough lead. I added 90KG
(198lb) of lead, but it still wouldnt go down. What i didnt mention
on the website was that i was forced to stop testing because the harbour
master came along to say that they had had an anonymous phone call from
some bloody do-gooder who pointed out that we were using the comercial
area of the harbour and didnt have a proper comercial dive team, which is
officially a legal requirement. So even though i had full permission
from the harbour, i was forced to stop on a technicality. They think
it was some missery that has the hump on with harbour and just wanted to
be awkward. Shame because I was about to load a pile of anchor chain
into the boat to get me more weight.</div>
<div> </div>
<div>The boat did seem to be very light at the back and i kept squirting
air into the forward tank to level it out. Thinking about it, i
suspect that the forward tank was settling into the correct position and
it was the aft tank that was riding high. Just need to get some
weight at the back. I had a slight list to port as well which i've
no idea where that came from. Again i will trim that up.</div>
<div> </div>
<div>Anyway, i was really pleased with how it went on my first day.
Im meeting my divers tonight who took a load of underwater pics
apparently, so i will see how they look later. Might put some on the
web if they are any good.</div>
<div> </div>
